3.19.4  Checklist – Initial start-up 

After thorough servicing or when the pump is to be put into service for the first time  
(initial start-up) the following checklist must be observed:

c

  Suction and discharge pipes are cleaned.

c

  Suction and discharge pipes are checked for leaks.

c

  Suction pipe is protected properly to prevent the ingress of foreign bodies.

c 

The characteristics of the pump unit and safety relief valve to be checked  

(pumptype – see name plate, RPM, working pressure, effective power, working  
temperature, direction of rotation, NPSHr etc.).

c

  Electrical installation complies with local regulations

c

  Motor voltage corresponds with mains voltage. Check terminal board.

c

  Make sure that the starting torque is sufficiently high (no star/delta starting will be used).

c

  Motor protection is adjusted properly.

c

  Direction of motor rotation corresponds with direction of pump rotation.

c

  Motor rotation (detached from unit) is checked.

c

  Safety relief valve (on pump or in piping) is installed

c

  Safety relief valve is positioned correctly. Flow direction of safety relief valve  

corresponds with suction and discharge lines.

c

  The set pressure of the safety relief valve is checked (see nameplate).

c

  Jackets are installed.

c

  Maximum pressure and temperature of the heating/cooling media have been checked.

c

  The appropriate heating media or coolant is installed and connected.

c

  The installation complies with the safety standards.

c 

Alignment of pump, motor, gearbox etc. is checked.

c

  All guards and safety devices (coupling, rotating parts, excessive temperature) are in place  

and operative.

c 

In case of pumps that may reach working temperatures of 60°C or more, ensure sufficient safety 
guards against accidental contact re in place.

c

  Monitoring system is operational.

3.19.5  Start-up

When the pump is to be put into service the following checklist and procedure must be observed:

c

  Pump is filled with liquid.

c

  Pump is sufficiently preheated.

c

  Suction and discharge valves are fully open.

c

  Start the pump for a short while and check the direction of rotation of the motor and that the 

magnetic coupling is not slipping.

c

  Start the pump and check suction of liquid (suction pressure).

c

  RPM of the pump is checked.

c

  Discharge pipe and seal are checked for leaks.

c

  Proper operation of the pump is verified.
